a K ,carlines each composed of two angle bars B it. known th t. I, E A P a secured together at their centers and divergcitizen of the United States, residing at on opposite sides thereof Chicago, in the county of Cook and State and",purlins crossing the ca'rlines and has of Illinois, have invented certain new and toned to both angle bars of each carline, so useful Improvements in Car-Roof C011- that the .pu'rhnsstrengthen the rigidity of t ti f hi h th f ll i i a ithe connection between the angle bars of the fication. carhnes- My invention relates in general to car My invention will be more .fully disclosed fram work, and mor rti ul rly t hereinafter with reference to the accomcar roof construction of the character covpanylng drawings, in which ered by my Reissue PatentNo. 13,297, the Flgure 1 1S a was t d upon a car roof, portlons thereof being broken an application copending'with this application. In-the roof construction-illustrated patent, the carlines are integral standard rolled v y improved carl nes. lug. .2 1s a perspect ve viewof my improved carline removed from the car each formed of an provide a thestructural characteristics covered by my isaid lines, while generically the same as the car- ]lines covered b sldes of said central ,downwardly and diverging from each other end part way toward the center and the divided parts of the ends spread apart at an angle to each other and secured at their-extremities to the side plates.

The ob ect of my present invention is to car roof framework possessing relssue patent, but in which the carmy'sald reissue patent, are specifically diflerent, in that they are each composed of two angle bars secured back to back atthe centra'l part of the carline with their horizontal flanges projecting in opposite directions from the tops of their vertical flanges, the bars upon the opposite part being inclined toward the car'sides to whichthe extremities of the vertical flanges :of the bars are se-' cured.

A further object of my invention is to provide in a car roof construction carlines of the generic character of the carlines covered by my said reissue patent, but which will not involve the splitting of the standard rolled beams and the subsequent bending apart of the split portions thereof, but while utilizing commercial rolled beams, wil not involve wardly inclined" diverging parts for attachment to the side plates.

, throughout the bod any splitting of them, but.

roof framework. Fig. 3 1s a sectional View on line 3 3, Fig. 2. Fig. 4 is a sectional view,

showing the attachment of the carline with Fig. 5 1s a view simia wooden side plate. lar to Fig. 4, showing the attachment of the carline to a steel side plate, and Fig; 6 is a bottom .view of one end .of the adjacent portion of the to which it is attached.

he same reference characters are used to designate the same parts in the several figures of the drawings.

The framework of the car roof comprises the usual side plates placed longitudinally of the car, purlins 41 and ridge beam 42. 'Transversely arranged directly be-- neath these frame members are'the carlines 43, each of which is formed of two angle bars 70 and 71 placed with two flanges in vertical contact and secured together y- Portion of the carthe carline and line. bars PlOjGCt in opposite directions from the tops of the vertical flanges andare provided with holes 46 through which pass'the bolts 46 for rigidly securing each of the angle bars composing each. carline to the ridge beam 42. The horizontal flanges of the angle bars are also provided with pairs of through the portions thereof holes 47 which underlie the purllns 41 and through which extend bolts 47 rigidly securing each angle bar of each carline to the intersecting portions of the purlins,

The angle bars of each carline diverge on opposite sides of the central portion of the carline, as shown at 73 and 74, and the extremities of the anglebars at each end of the The horizontal flanges of theangle The vertical flanges of the angle bars in each carline throughout the portions thereof which are in contact are rigidly secured together bysuitable fastening means, such,

for'instance, as rivets 7 2.

Each carline is given an arched form transversely of the car roof, the portions thereof on opposite sides of the ridge beam being deflected downwardly toward the car sides to the side plates of which the ends of the divided end port-ions of the carlines are secured.

In the form of car roof which I have preferred to show in connection with my improvements, the usual fascia board 49 is used and the bolts 48 pass through this fascia boardand are secured in position by the nuts '50. The corrugated metal plate 51 lies immediately above theside plates 7 5 and the purlins -41, and is embedded in the roof beam 42 at its inner edges. Immediately above this corrugated metal plate are placed the sub-purlins 52, upon which are placed the .roof boards 54. The roof boards. are

also spaced from the corrugated plates 51 by the supplementary ridge members 53 and the supplementary plates 55, .as will be clearly seen in Fig. 1.

The diagoal 'corner tached-to the side plates in similar manner tothe forked ends of the carlines, and also to i the end frame members 58. These braces 57 also serve in making the framework veryI strong and rigid and especially adapted to: car s1 --It willbe understood that my im roved.

'- carlines are adaptedfor all kinds o roofs, although I have illustrated them in con-Q nection with a roof which is madeup of a. metal roof within the usual wooden roof.

resist diagonal stresses.

My improved carlines are adapted to any form of roof structure inwhich said roof mustbe supported by members arranged transversely ofthe car'body, a'ndin which stresses. The forked end portions of 'my.im-'

proved carlines very readily transmit the; said diagonal stresses from the side plates to fthepurl1ns and to the inner portionsof the.

' In Figs have illustrated my proved carhne in connection with channel necessary resistance--10 vertical stresses re braces 57 are at-I said members are subjected to diagonalsulting from the weight of. the roof and ends ofT't-he carlines afford a wide support which has 'the efiect of preventing the carlines from being tilted longitudinally of centers, and the diverging ends also serve 1n connection with the car sides to which rigidity necessary to preserve its original form.

carllnes serve to brace the roof against diagonal parts perform, the usual load sustaining functions of the wholecarline. In practice, Iahave found that this carline is unusually strong and rigid in proportion to the amount of material employed therein, and a-roof framework comprising such carlines has great durability.

I do not in this application claim 'generically a car roof construction comprising carlines extending completely across the car and secured to and supported upon the side walls so as to "afford an unobstructed space between the carlines, each of the carlines toward the sides thereof and having their read apart diagonally toward the es so as to form arches braced parts 3 an approx mately horizontal truss, inas much as such generic inventionisclaimed in my said ReissuePatent No. 13297, but

cific form of said generic invention in which secured back to back at the centenof the carline and spread diagonally apayt'on opextremities I claim:

to the side plates.

.1; In a carroof, the combination with a mental-y angle bars, eacfh angle bar having a vertical flange and a flange 'ektending outwardly at a right angle from the upper edge of said vertical flange, the vertical flanges of said two angle bars lying in parallel relation for acertain distance upon each side of the longitudinal center ofeach carline and there secured together, said angle bars they are secured toform "an approximately horizontal truss capable of resisting high The diagonal portions at the ends of the havingv an arched form and sloping down-- wardly from the central part of. thecar set of carlines, each comprising two comp1e-.

service strains. gTh'e outwardly diverging the car 'around the chordsof the arches as l agonal strains. At the sametime these diend portions. bifurcated and the bifurcated against tilting longitudinally of the car and so as to impart to the entire roof structure in my present application I claim the specarlines possessing the structural characteristics above on lined are formed of angle bars -,posite sides thereof and secured at their upon the opposite sides of said center por- 1 'set of carlines, each comprising two comple mentary angle bars, each angle bar having a verticalflange and a flange extending outwardly at a right angle from the upper edge of said 'vertical flange, the vertical flanges of said two angle bars lying in parallel relation for a certain distance upon each side of the longitudinal center of each carline and there secured together,- saidangle bars upon the opposite sides of'said central portion inclining downwardly and diverging from each other, of purlins extending across the carlines, and means securing each purlin to, the horizontal flange of each of the anglebars forming each of said carlines.

3. In a car roof framework, the combination with side plates, of metal carlines each comprising two complementary angle bars, each angle bar having a vertical flange and a flange extending outwardly at a right angle from the upper edge of said vertical flange, the vertical flanges of said two angle bars lying in parallel relation for a certain distance uponeach side-of the longitudinal center of the carline and there secured together, said bars upon the opposite sides of said central portion inclining downwardly and diverging from each other, the

vertical flanges of the corresponding ends of the angle bars of each carline being bent to lie in the same plane, means securing the flanges at the ends of the angle bars forming the carlines to' the side plates, \purlins overlying the said carlines, and means securing each pnrlin to the oppositely projecting flanges of the angle bars of'each of said carlines.

4. In a railroad car, side walls and metal carlines, each having an arched form and sloping downwardly from the central part of the car toward the sides thereof, said carlines extending completely across the car and secured to and supported solely upon said side walls, thus affording an unob' structed space beneath said carlines, each of said carlines comprising two flanged metallic bars having parallel intermediate portions secured together, each of said bars having its opposite end portions disposed at an angle to the intermediate portion, whereby the carline as an entirety has bifurcated ends, the bifurcated end parts diverging toward the car sides to which they are secured, whereby the arches formed by'the carlines are braced against tiltingilongitudinally of the car and whereby ,the entire structure forms an approximately horizontal truss.

In testimony whereof, I have subscribed my name.
